Well, bad luck hit again.
The passenger side air injection hose/check valve
let go and of course the wire harness that goes to
the PCM(or ECM) was right there and melted all the
insulation off the wires.
99' 2 dr Blazer.

I'm thinking of getting some connectors and doing a splice.
Mainly to see if the PCM and other electronics are o.k.
It's about 64/65 wires.(one looks sheilded)
Maybe later try to get a harness from a boneyard or the dealer.

Most of the ECM and PCM fuses blew.

Any suggestions from experienced GM techs or others are
appreciated.

all computer circuits should/must be low resistance therefore must be soldered. no crimps no wire nuts will be better off with new harness but at what cost?

$600 and change from the dealer. After I heard
the 600 part I blanked out.

Used, a boneyard told me a "couple" hundred.


It looks like a pain to do.

Sorry man, that sounds pretty crazy.

I would look on ebay, I've seen them for like $5.
